This is a question on behalf of my friend.
His kid brother installed a password on his windows 7 home premium desktop and now he forgot. How does he get in?
Since the data is backed up into a flash drive, i suggested nuking using DBAN and reinstalling OS.
To complicate matters further, his CD drive doesn't work. In that case, what options does he have available to recover his password?
Can DBAN be run from a bootable pendrive?

I made a bootable USB drive with Offline NT Password http://pogostick.net/~pnh/ntpasswd/ You can then just locate the user profile he logs in with and blank the password.
Just make sure the BIOS of the PC is set to boot off USB first. (Or whatever you decide to put Offline NT Password on, if you burn it to a CD then make sure the BIOS is set to look at the CD first)

The instructions look pretty daunting with having to load drivers from floppy. Simplify them please or maybe they're not needed?

On the website under this link is has a method of downloading the USB files under the Download section. Directly under the Download section it has How to make an bootable USB drive pogostick.net/~pnh/ntpasswd/bootdisk.html

@FasihKhatib - Sounds like you should just replace the drive in question.

This method works really well and is easy.... (the destructions are a little less intimidating then they appear...) Believe me, if I can figure it out, then so can you :-D

I can't do this because the bootable USB with OS says there's some boot error. I knew his trick :) :)

Then download some LiveCD image (e.g. Ubuntu 12.04 LTS) and burn it to a flash drive. Use the file browser (Nautilus) instead of the command line if you don't know your way around Linux.

I forgot to mention that he tried making a bootable USB containing OS but computer flashed an error saying there's some problem with boot

Well, that could be anything from faulty BIOS to incorrect boot order to USB not created properly to USB broken to... well, I think you get the drift. It' very hard to say what's wrong with out seeing a specific error message.

@Sandokan - This answer really needs more information. When compared to the answer by Dennis this answer doesn't help the lack of technical knowlege by the author ( based on his earlier comments ).
